滇西北横断山区全新世古植被与古气候的演变
THE SPORE-POLLEN ANALYSIS AND SIGNIFICANCE OF THE NORTH-WEST YUNNAN PLATEAU IN THE HENGDUAN MOUNTAINS
【摘要】 通过滇西北横断山区4个泥炭剖面的孢粉分析表明,全新世以来本区植被与气候主要经历了5个发展阶段。晚更新世与全新世的界限可定为12000年。各地点的泥炭堆积速率介于0.84~0.30毫米/年之间。
【Abstract】 Five pollen diagrams reveal palaeophytes and palaeoclimate changes during the Holocene in the North-West Yunnan Plateau of the Hengduan Mountains.The Holocene period can be divided into five stages,the ve- getation and climate of each site have nothing in the common with each other. In the North-West Yunnan Plateau,swamp isn’t developed at the same time,the initial stage of swamp-forming is early period of the early Holocene,die out at late period of the middle Holocene.
